Analysis of Polyphenolic Composition of a Herbal Medicinal Product—Peppermint Tincture

et al. 2019

View full text Add to dashboard Cite

The pharmacological activity of peppermint leaf (Menthae piperitae folium) for medical use is mainly attributed to the presence of essential oil, which, according to the European Pharmacopoeia (Ph. Eur.), should constitute not less than 12 mL/kg of raw material. The content of polyphenols in peppermint-based preparations, except peppermint leaf dry extract, has not yet been considered as an essential parameter in the pharmacopeial assessment of peppermint quality. This study concerns the evaluation of the presence of representatives of polyphenolic compounds in 23 commercial peppermint tinctures (ethanolic extracts) purchased in pharmacies in Poland. The non-volatile polyphenolic fraction was investigated, and the presence of flavonoids and phenolic acids was quantified. High performance liquid chromatography coupled with a diode-array detector (HPLC-DAD) and an electrospray ionization mass spectrometer (U(H)PLC-ESI-MS) were used in the experiment. The study showed that eriocitrin, luteolin-7-O-rutinoside, and rosmarinic acid were the main polyphenolic components of the peppermint tinctures, as previously reported for peppermint leaf. Despite this, the research shows the extremely diverse content of the mentioned compounds in analyzed commercial medicinal products. In light of these results, it seems that the pharmacopeial assessment for the peppermint leaf (Ph. Eur.) and peppermint tincture (Polish Pharmacopoeia (FP)) requires correction and supplementation.

“…Peaks 2 and 4 with pseudo-molecular ions at m/z 305.0700 and 387.1661 were tentatively characterized as 12-hydroxyjasmonic acid derivatives, tuberonic acid sulphate and tuberonic acid O-glucoside, respectively [40]. Peak 26 (m/z 563.2124, fragment ion: 387) was described as a medioresinol derivative [38,40].…”

“…In the case of the mixture, C. nobile [8] and L. nobilis [21] seemed to have a greater influence on the phenolic composition, with luteolin-O-glucuronide being the major peak detected. Tuberonic acid hexoside (peak 7, [M − H] − at m/z 387) showed fragments at m/z 207, which corresponds to the aglycone after loss of hexose [M−H−162] − , and has been previously described in other plants of the Lamiaceae family [22]. Nine compounds were tentatively identified in mix 2.…”

Infusions of Herbal Blends as Promising Sources of Phenolic Compounds and Bioactive Properties

et al. 2020

Several plants have been used for medicinal applications and have been traditionally consumed as decoctions and infusions. Although some herbs are used alone as a beverage, they are often blended in mixtures to maximize their effects. Herein, the nutritional characterization of six infusions from herbal blends was evaluated using the official methods of analysis (AOAC international). A further characterization of the individual phenolic profile was also performed by HPLC-DAD/ESI-MSn, and finally bioactive potential was determined by evaluating the antioxidant, cytotoxic, anti-inflammatory, and antimicrobial activities of each blend. The wide variety of plants in each sample led to variability in the results for all analyzed parameters. However, blends containing 15% Laurus nobilis L. and 15% Juglan regia L. in their composition showed higher sugar content and energy contribution; higher concentration of phenolic compounds (phenolic acids and flavonoids); greater antioxidant, cytotoxic, and anti-inflammatory capacity; and also better antimicrobial effects against all the tested bacterial and fungal strains. Further studies will be necessary to evaluate the real synergistic effects that these two species show in the presence of other plants, and to evaluate their potential for application in various food, pharmaceutical, and nutraceutical products as infusion preparations.

“…The negative ion mode provides the highest sensitivity and results in limited fragmentation making it most suited to infer the molecular mass of the separated polyphenols especially in cases where concentration is low. A tentative identification of compounds was carried out using comparisons of the m/z values, the RT and the fragmentation patterns with the MS 2 spectral data taken from the literature (Banno et al, 2004;Vallverdu-Queralt et al, 2012;Zhou et al, 2014;Spinola et al, 2015;Cirlini et al, 2016;Pandey et al, 2016;Sharma et al, 2016;Marzouk et al, 2018;Sun L. et al, 2019;Goufo et al, 2020;etc. ) or the data bases (MS2T, MassBank, HMDB).…”

Polyphenols of <i>Perilla frutescens</i> of the family Lamiaceae identified by tandem mass spectrometry

et al. 2022

Perilla frutescens is mainly cultivated as an oilseed crop. Perilla seeds contain 40-53 % of oil, 28 % of protein.The growing season is 100-150 days. In Russia, perilla is grown in the Far East, where the yield is 0.8-1.2 t/ha. Perilla of different geographical origin has its own special, sharply different features that characterize two geographical groups: Japanese and Korean-Chinese. These groups differ from each other in the length of the growing season, the height of plants, the color of the stem, the surface and the size of the leaves, the shape of the bush, the shape and size of the inflorescences, the size of the cups, the size and color of the seeds. P. frutescens contains a large number of polyphenolic compounds that are biologically active components. The purpose of this research was a metabolomic study of extracts from leaves of P. frutescens obtained from the collection of Federal Research Center the N.I. Vavilov All-Russian Institute of Plant Genetic Resour ces, grown on the fields of the Far East Experiment Station -Branch of Federal Research Center (Primorsky Krai, Russia). To identify target analytes in extracts, HPLC was used in combination with an ion trap. Preliminary results showed the presence of 23 biologically active compounds corresponding to P. frutescens. In addition to the reported metabolites, a number of metabolites were newly annotated in P. frutescens. There were hydroxycoumarin Umbelliferone; triterpene Squalene; omega-3 fatty acid Stearidonic [Moroctic] acid; higher-molecular-weight carboxylic acid: Tetracosenoic acid and Salvianic acid C; lignan Syringaresinol and cyclobutane lignan Sagerinic acid, etc. A wide range of biologically active compounds opens up rich opportunities for the creation of new drugs and dietary supplements based on extracts of perilla of the family Lamiaceae, subfamily Lamioideae, tribe Satureji and subtribe Perillinae.
